Bathroom storage is where renovations diverge most sharply between what looks good in the listing photo and what works on a Tuesday morning. The medicine cabinet has been the residential bathroom storage default for decades and remains the most space-efficient option because it claims space inside the wall. Open shelving is the design-magazine alternative that photographs beautifully and demands more curation than most households actually deliver. The right pick depends on your bathroom’s wall construction, your visual tolerance for products on display, and how much storage you genuinely need. This guide walks through both.
The medicine cabinet: face-height storage that disappears
A medicine cabinet is a recessed or surface-mount cabinet behind a mirrored door, mounted at face height above the vanity. The cabinet holds the daily-use items that you want at face level: toothbrush, toothpaste, daily skincare, current makeup, daily medications. The mirrored door doubles as the vanity mirror.
The recessed install is the residential gold standard. The cabinet box sits inside the wall cavity, between the studs, with only the door projecting into the room. The result is roughly 50 to 100 cubic inches of storage that takes no room footprint and integrates seamlessly with the wall surface.
The surface mount install attaches the cabinet box to the wall surface and projects 4 to 6 inches into the room. Surface mount works on walls that cannot accept a recessed install (load-bearing walls, exterior walls, wet walls with plumbing). The protrusion is noticeable but not problematic in most bathrooms.
Standard recessed cabinet dimensions are roughly 16 to 24 inches wide, 24 to 36 inches tall, and 4 to 5 inches deep. Larger cabinets are available, including double and triple cabinets that span 36 to 60 inches wide and provide enough storage for a two-user primary bathroom.
The lighting integration in modern medicine cabinets is significant. Many premium cabinets include integrated LED lighting around the mirror perimeter or above the mirror that provides vanity-task lighting in addition to the storage function. The combination cabinet-plus-lit-mirror is one of the cleanest specifications in current bathroom design.
Material cost runs 150 to 500 dollars for a basic recessed cabinet, 400 to 1500 dollars for a lit cabinet, and 800 to 3000 dollars for premium double or triple lit cabinets. Install adds 150 to 500 dollars for a recessed install (drywall work plus framing modification) or 60 to 200 dollars for a surface mount.
Open shelves: the design-forward alternative
Open shelves are horizontal boards mounted to the wall, holding bathroom items in plain view. The shelves can be wood, glass, metal, or stone, and the mounting can be wall-bracket, floating-shelf, or integrated into surrounding cabinetry.
The aesthetic appeal is the primary driver. A well-curated open shelf display reads as a designer choice. Folded clean towels, a glass jar of cotton balls, a small plant, a decorative bottle, and a single piece of art on a shelf creates the Instagram bathroom that the design magazines feature.
The functional limitation is the curation requirement. Open shelves only look good when the items on them look good. The cap to that constraint is brutal: actual daily-use bathroom items (medicine bottles, toothpaste tubes, hair products, deodorant) do not look good on shelves. The household either has to commit to keeping daily items hidden elsewhere (vanity drawers, a separate medicine cabinet) and using the shelves only for curated items, or the open-shelf aesthetic disintegrates within weeks.
Open shelves also accumulate dust, lint, and water spots faster than closed cabinets, because the items on the shelves are exposed to bathroom humidity and aerosolized soap residue. Items need wiping every 1 to 2 weeks to stay presentable. Closed cabinet contents need wiping every 2 to 6 months.
Material cost runs 30 to 200 dollars per shelf for basic wood or metal, 100 to 500 dollars per shelf for premium materials or floating-shelf hardware. Install is 30 to 90 minutes per shelf.
The hybrid: closed cabinet plus curated shelves
The configuration that actually works in most real households is the hybrid: a medicine cabinet (or vanity drawer storage) for the visually noisy daily items, plus 1 to 3 open shelves for the curated display items.
This pattern lets the homeowner have the design-magazine aesthetic where it photographs (the open shelves with clean towels and a plant) while keeping the everyday clutter hidden behind a mirrored door. The daily routine works because the items that get reached for every morning live behind the medicine cabinet door; the items that live on the open shelves are reached for infrequently or are purely decorative.
The hybrid also handles guests well. Guests see the curated open shelves and the clean lit mirror over the vanity. They do not see the inside of the medicine cabinet unless they specifically open it.
The hybrid install cost is roughly the cabinet cost plus the shelf cost, with no compounding savings. Plan 600 to 2000 dollars for the combined setup on a mid-priced remodel.
Vanity storage as the third leg
The vanity itself is the third storage zone and is often underutilized in renovations. A 30 inch single-sink vanity provides roughly 8 to 12 cubic feet of cabinet storage below the sink, with drawer or door configurations.
Drawer-based vanity storage is significantly more usable than door-based storage. Drawers let the user see and access items in the back of the cabinet without bending and reaching. The drain works around drawer frames with notched cuts in the back of each drawer.
A vanity with 3 to 4 drawers below the sink, plus a medicine cabinet at face height, plus 1 to 2 open shelves for curated items, covers the storage needs of most primary bathrooms without the homeowner ever feeling cramped for storage. This is the configuration that residential bathroom design has converged on over the past decade.
Picking for your bathroom
For a primary bathroom remodel, install a lit recessed medicine cabinet (or a double cabinet for two-user bathrooms), a drawer-based vanity below the sink, and optionally 1 to 2 open shelves on a wall that has room for them. This is the residential standard for a reason.
For a small bathroom with limited wall area, prioritize the medicine cabinet and skip the open shelves. The closed storage delivers more practical value per square inch.
For a powder room with no vanity (a pedestal sink or floating console sink), install a small surface-mount cabinet plus 1 to 2 narrow open shelves above the toilet for hand towels and decoration.
For a wall that cannot accept a recessed cabinet, install a surface-mount cabinet (the 4 to 6 inch protrusion is a small price for the storage gain) plus open shelves where wall space allows.

Frequently asked questions
Can I install a recessed medicine cabinet on any bathroom wall?+
No. The wall has to be either a non-load-bearing partition with empty stud bays, or a load-bearing wall where the stud bay can be modified with a header. Exterior walls usually contain insulation and sometimes plumbing or wiring, which makes recessing impractical. Wet walls (the wall that holds the plumbing for the shower or the vanity) often contain pipes and vents that block the stud bay. Before buying a recessed cabinet, open a small inspection hole in the intended location or have an electrician and plumber scope the wall. If the wall does not accept a recessed install, switch to a surface-mount cabinet.
Are open shelves practical for daily bathroom items?+
Yes for the items that look good on display (clean towels, decorative bottles, plants), no for the items that do not (medicine bottles, toothpaste tubes, hair products). The hybrid that works is open shelves for the curated items plus a closed medicine cabinet or under-vanity storage for the visually noisy items. A bathroom that uses open shelves as the only storage will look magazine-cover for the first week and cluttered or chaotic by month two unless the homeowner is willing to keep everyday items hidden in a drawer.
What goes inside a typical medicine cabinet versus what should not?+
Daily items that benefit from being at face height go inside: toothbrush, toothpaste, dental floss, daily medications, contact lens supplies, skincare in current rotation, makeup in daily use, a small first-aid kit. Items that should not go inside: actual medications in long-term storage (the bathroom humidity degrades pills faster than a bedroom drawer), backup product inventory (use vanity drawers), bath towels (too big), and anything that needs to be cool and dry. The misnomer of the name confuses people; modern medicine cabinets are really face-height daily-rotation cabinets.
How deep should a medicine cabinet be?+
4 to 6 inches is the residential standard for recessed cabinets and is sufficient for most face-height bathroom items. 6 to 8 inches surface-mount cabinets give more storage but protrude further into the room, which matters in tight bathrooms where the cabinet is over the sink. The depth balance is: bottles of cleanser, toner, mouthwash, and most skincare fit in 4 to 5 inches. Tall items (hair spray cans, larger bottles) need 6 inches or live somewhere else. Most bathrooms benefit from a 5 inch recessed cabinet plus separate storage in the vanity for tall items.
Do open shelves work better in a small bathroom or a large bathroom?+
Large bathrooms, surprisingly. A small bathroom benefits more from closed storage because the visual clutter of products on open shelves is louder in a small space where the eye cannot rest on negative space elsewhere. A large bathroom can absorb open shelves visually because the eye has other places to look. The exception is a small bathroom designed intentionally minimal, where the homeowner commits to keeping only 2 to 4 items on the open shelves and everything else hidden in the vanity. Most real households do not maintain that discipline.
